Be it known that 1, JOHN E. FINLEY, of Memphis, county of Shelby, and State of Tennessee, have invented a new and useful Improvement in Chums; and I do herehy declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which.

A, staff; B, thimble; C C C, flanges;- DD, air-cups; E, centre thimble; a, thumb-screw; F F, flanges; G, screw; H,nut; I, key.

I construct my churn inthe' usual tub form. To. the staff A, I attach two wheels 0 G O F F, with four flanges each, with-the flanges set in such a manner that when the staff A is operated the flanged wheels 0 O O F F will revolve in counter or opposite directions. To the flanged wheels 0 G G F F, I attach two air-cups D D, in such amanner as to carry the air into the cream. Between the flanged wheels 0 O O F F, I place a thimblc, E, with the thumb-screw e to keep the wheels 0 G C F F in place. At the bottom of the thimbie B. I place the screw G, with the nut H and key I, in-suche way thet the wheelsG O O F F, with the middle thimbl'e E, can be'removed at any time for the purpose of cleansing.- The object of the key Lie to prevent the nut H from becoming unscrewed when the dasher A is operated.

The object of my invention is to give to' the flung-ed wheels G C C F B an opposite revolving motion, while; the air-cups D D carry the airthroughout the cream, thus hastening butter-marking. v

.1 claim the ,comhination ofthe flanged wheels 0 G0 F F with the ai-r-cupsD D, the thimble B, and middle thimblc E, and thumb-screw c, the nut H and key Iifor the purpose herein set forth. I
